C60衍生物与C60混合物中富勒烯的生长研究

富勒烯分子生长方面的研究，对于富勒烯的基础研究以及潜在应用有着重要的意义，因此引起了科学界的广泛兴趣和研究，Yeretzian1]、Campbell2],Rao3]等人相继用不同的实验方法对C60的融合作了详细研究，但C60的生长动力学过程依然是个悬而未决的问题．我们实验室已对C60的正负离子解离以及C60加成衍生物中C60的解离和生长作了较深入的研究：发现C60正负离子解离时电荷具有不同的转移通道，即C朋解离时电荷留在碳笼上，而C60解离时电荷易转移到小碳簇上，且C60解离以较缓慢的笼子收缩过程进行间．衍生物基团（如节基、薛基）对C。。…

Formation of Fullerenes in C_(60) Derivatives and C_(60) Mixtures

The negative ion time-of- flight mass spectra of C60 benzyl derivative and C60/polystyrene mixtures were investigated by UV laser desorption. We found that the aggregation of C6o in derivatives and ndt1lres was very different. The mechanisms of the coalescence of C6o and the growth of C60 by capturing small carbon clusters were discussed. We thought that in derivatives the nascent C60 formed from the rupture of the radicals can easily coalesce into large fullerenes through co1lisions, while in mixtures C60 and small carbon clusters can grow into large fullerenes only when C60 and small carbon clusters were in proper ratio, but no coalescence of C60 was observed.
